|HippophaŽ rhamnoides||Sea Buckthorn|
Origin: E England
Sea buckthorn has been widely planted on sand dunes in Northern Ireland, particularly at Murlough in Co Down and Portstewart Dunes in Co Londonderry. It has become a serious nuisance on both dune systems, forming impenetrable thickets which blanket out the native dune vegetation.
These three photographs show the plant on the dunes at Portstewart.
|The top and middle photographs show marram grass (Ammophila arenaria) in the foreground - part of the natural vegetation succession of local dune sysytems - with a dense thicket of silvery-leaved sea buckthorn behind it.|
|In one area (bottom photo) the sea buckthorn has grown very tall, forming trees and producing a dense shady woodland.|
